Application filed January 26, 1927. Serial Ito. 163,?20.

he object of the invention is to provide a rail joint construction wherein the tread of the car wheel will be fully supported as it passes over the joint, thereby avoiding the difficulty of peening or rounding over the ends of the rails when they separate due to contraction of the track; and to provide a rail chair in which the desired aligned re lation of connecting rails is effectively main tained.

lVith this object in view, theinvcntion consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawings, wherein:

Figure 1 is a plan view of the invention.

Figure 2 is a side elevational view. 7

Figure 3 is a transverse sectional view on the plane indicated by the line 3-3 of Figure 1.

Figure lis a transverse sectional view on the plane indicated by the line 4-4 of Figure 1.

Figure 5 is a longitudinal sectional view on the plane indicated by the line 55 of Figure 1.

. The rails 1 and 2 at their adjacent ends are cut away, as indicated'at 8, to provide a space for the cross-leg of the T head at which is formed integral with the side plate 5 of the rail chair 6, the side plate being an integral part of the chair and shaped to lie against the base flange and web of the rail, leaving the upper surface ot the T-head in. the plane or the rail treads.

A. complemental plate 7 of the same general form as the plate portioi'i :3 is dis on the opposite side of the rails but is sep rate from the chair, being removabiy mounts ed therein and secured to the plate 5 and to plate 7, having ribs l l engaging grooves 15 formed in the diagonal edges ot the side plate.

To provide for effectively securing wedge action in assembling the construction, the

wedges are operatively connected by a bolt 16 extending longitudinally through the two, the head 17 abutting the outer end of one wedge and a nut 18 abutting the outer end of the other wedge. Tightening the nut on the bolt obviously effects movementof the wedges toward each other with the exertion of a lateral pressure on the movable plate 9, so that thetwo side plates are brought into lirm clamping engagement with the rails to insure perfect alignment thereof.

Since the "IT-head constitutes an insert between the connecting ends of the rail and is laterally inset in the tread portion, the breaks of the joint are staggered so that in the passage of the wheels over the rails, the tread portions pass onto the T-heads before having left the rails and thus a tendency to round or peen over the extremities of the rails is avoided.

The invention having been described, what is claimed as new and useful is:

1. In combination with connected rails, a rail chair having an integral side plate lying against the web and flange portions of the rails, a complcmental removable plate seated in the chair and lying against the opposite sides of the rails and means for effecting clamping action of the removable plate against the rails and comprising elements mounted at the remote ends of the chair and engaging the removable plate and operated by a single actuating means.

9.. In combination with connected rails, a

rail chair having atone side a guide rib and at the other side an integral side plate lying against the web and flange portions of the rails, a complen'umtal removable plate seated in thechair and lying against the opposite sides of the rails, means for eliecting clam ing' action of the removable plate against the rails and comprising reversely disposed wedges having sliding engagement with the guide rib, the removable plate having a double inclined edge with which said wedges en age, and a oonnecting bolt extending longitudinally through both of said wedges.

3. In combination with connected rails, a rail chair having at one side a guide rib and at the other side an integral side plate lying against the web and flange portions of the. rails, a complemental removable plate seated in the chair and lying against the opposite sides of the rails, means for effecting clampmg action of the removable plate against engagement with both the chairand the removable plate and consisting of ribs on the Wedges engaging grooves formed in the 1 double inclined edge of the removable plate and lateral ribs on the opposite sides of the wedges engaging a groove undercut in said guide rib.
